SED scripting - exclude self

Question

I would explain my issue but it is easier just to paste the code

test.sh

sed -i '/192.168.1.1/d' *

I want it to exclude itself in this search, how would I go about doing that?

Answer 1

The simplest solution is to use bash's extended pattern syntax.

shopt -s extglob
sed -i '/192.168.1.1/d' !(test.sh)

The pattern !(test.sh) matches everything except test.sh.
